The productivity of animal agriculture in developing countries will need to be substantially increased in order to satisfy increasing consumer demand, to more efficiently utilize scarce resources and to generate income for a growing agricultural population. Biotechnology has the potential to improve the productivity of animals via increasing in growth, carcass quality and reproduction, improved nutritional quality, safety of food, improved health and welfare of animals and reduced waste through more efficient utilization Agricultural biotechnology is one area of application of biotechnology involving applications to agriculture and the application has long been source of innovation in production and processing, extremely impacting the sector. Agricultural biotechnology has been practiced for a long time, as people have sought to improve agriculturally important organisms by selection and breeding. This includes plant breeding to raise and stabilize yields; to improve resistance to pests, diseases and abiotic stresses such as drought and cold; and to enhance the nutritional content of foods. Biotechnology is being used to develop low-cost disease-free planting materials for crops such as cassava, banana and potato and is creating new tools for the diagnosis and treatment of plant and animal diseases and for the measurement and conservation of genetic resources. Modern biotechnology has the potential to provide new opportunities for achieving enhanced livestock productivity in a way that alleviates poverty, improves food security and nutrition and promotes sustainable use of natural resources. The major cause of poor livestock productivity in tropical regions of the world is inadequate nutrition. Low-quality forages are a major component of ruminant diets in the tropics. The lack of quality of ruminant feeds is caused by a high content of lignified crop residues and mature grasses, usually associated with a low content of nitrogen, phosphorus and sulfur. The shortage of feed in most developing countries and the increasing cost of feed ingredients mean that there is a need to improve feed utilization. Animal feeds and feeding practices are being changed by biotechnology to improve animal nutrition and to reduce environmental waste. The ultimate goal of using biotechnology in animal nutrition is to improve the plane of nutrition through the use of enzymes to improve the availability of nutrients from feed and to reduce the wastage of the feed.

Organocatalysis, where organic molecules like α-amino acids, α-hydroxy acids, nucleic acids, carbohydrates are employed to catalyze organic transformations such as the aldol, Mannich and Michael reactions is a rapidly expanding field of organic synthesis. Operational simplicity, ready availability of the catalysts, selectivity, efficiency and low cost make them an attractive alternative to metal-mediated organic transformations. Although organocatalysts have many attractive features, this catalytic system also suffers from often high catalyst loading or poor solubility of the catalyst in organic solvents. Recently, ionic liquids, PEG, montmorillonite clays have been demonstrated to be good supports helping to overcome the limitations mentioned. These supported systems offer accepatble trade-offs in terms of yields and selectivity with the added advantages of recyclability of the catalyst. This review compares various supported and unsupported aminocatalysts mainly focusing on C-C bond forming reactions.

Several methods to determine amino acids and vitamins in biological and pharmaceutical samples have been reported. Thin layer chromatography (TLC) finds its place when the relatively costly equipment required by other methods is unavailable. This review covers the 1991–2010 literature on TLC/HPTLC (high performance thin layer chromatography) amino acid and vitamin determinations. It gives an overview of the special features as well as the problems in TLC/HPTLC determinations of amino acids and vitamins. Various chromatographic systems useful in amino acid and vitamin identification, separation and quantitation of are presented in tabular form. Future prospects of TLC/HPTLC for amino acid and vitamin determinations are also discussed. [...]
